/*
 * InteliaOps · Public site motion layer
 * ------------------------------------
 * Purpose:
 * - make the public site feel alive without turning it into a visual demo;
 * - reserve persistent motion for concepts that represent flow, processing,
 *   anticipation and progression;
 * - keep text and calls to action visually dominant;
 * - remain fully decorative: no animation carries information by itself;
 * - respect the user's reduced-motion preference.
 *
 * This stylesheet is intentionally scoped to .v4-site so it does not affect
 * the authenticated Client Portal that ships in the same application bundle.
